Jessica Simpson opened up to Oprah Winfrey about John Mayer’s graphic descriptions of their sex life and her weight issues, according to a new report.

The 29-year-old, who famously remained a virgin until her marriage to fellow singer Nick Lachey when she was 22, told the chat show queen she was embarrassed by Mayer’s comments to Playboy magazine.

Mayer said of his relationship with Simpson in the interview: “Sexually it was crazy.”

“It was like napalm, sexual napalm. Did you ever say, ‘I want to quit my life and just f—ing snort you? If you charged me $10,000 to f— you, I would start selling all my s— just to keep f—ing you.'”

According to Us Magazine, Simpson said in an episode of “The Oprah Winfrey Show” to air Wednesday: “I don’t want people to know how I am in bed!”

At first she said she’s not angry but then added, “I’m — well, I’m a little bit angry … I’m a little bit angry.”

Mayer later apologized for the interview and said he was “an a–hole.”

Simpson dated Mayer for almost a year after her divorce from Lachey in 2006.

The sometime actress told Winfrey she also struggles with criticism of her weight, including her much talked about appearance in a pair of high-waisted jeans at a Florida chilli cook-off in 2009.

Critics slammed the once svelte 5-foot-3 Simpson for her new, larger figure and pictures of the singer were splashed across tabloids and her outfit labeled “mom jeans.”

“It’s a really hard thing for me to talk about,” Simpson said.

She told Winfrey she was anything but fat during that time.

“You were a size 4 and people were calling you fat?” Winfrey exclaimed.

When she slipped into jeans shorts for 2005’s “The Dukes of Hazzard,” Simpson said, “I didn’t weigh 90 pounds. But I was — I was definitely smaller. But that was Daisy Duke, that’s a role. I was playing a role. I don’t want to look like Daisy Duke every day. I don’t want to wear a bathing suit every day.”
